“…In this study, the growth of earthworms among different treatments was closely related to the feed quality (Lim et al 2012). Figure 3 shows that the number of earthworms started increasing on week 6 for treatments of E1:D2 (18 earthworms), E2:D1 (15 earthworms), E1:D3 (14 earthworms) and E3:D1 (12 earthworms).…”

“…Generally, waste with high lignin contents (such as empty fruit bunches in this study) is not favorable for most of the earthworms (Shak et al 2014). Also, the high lignin contents in the waste inhibit microbial activities (Lim et al 2012). Therefore, cow dung was acted as a complementary waste not only to reduce the processing time but also to improve the quality and successful conversion of wastes into vermicomposts (Vig et al 2011).…”

Vermicomposting is a process to biotransform organic solid wastes into valuable product, namely vermicompost using epigeic earthworms. Vermicomposting technology may provide a low-input basis for sustainable management of organic solid waste. The present study was to investigate the suitability of oil palm empty fruit bunches to be reused as feedstocks of Eudrilus eugeniae for the duration of 12 weeks. Empty fruit bunches were mixed with cow dung in different ratios to produce five different treatments for laboratory screening of solid waste. The growths of E. eugeniae were monitored weekly. All treatments encouraged the growth of E. eugeniae except the treatment with empty fruit bunches alone. The maturity and quality of vermicompost were assessed through carbon-tonitrogen ratio, calcium, phosphorus, potassium and magnesium. Generally, all treatments showed increases in total contents of calcium (39.38-373.17 %), phosphorus (15.15-390.54 %), potassium (45.55-153.66 %) and magnesium (55.86-370.93 %) but a decrease in carbon-tonitrogen ratio (11.24-76.24 %) after 12 weeks of vermicomposting process. Besides, parameters such as pH and electrical conductivity were also investigated in this paper.Among all the treatments investigated, empty fruit bunches that were mixed with cow dung in the ratio of 2:1 were biotransformed into the most superior quality vermicompost (carbon-to-nitrogen ratio, 18.53; calcium, 7.76 g/kg; phosphorus, 3.63 g/kg; potassium, 12.81 g/kg; and magnesium, 4.05 g/kg). In conclusion, vermicomposting could be used as an efficient technology to convert empty fruit bunches into nutrient-rich organic fertilizers if the wastes were mixed with cow dung in an appropriate ratio.

“…Many researchers reported, RH is used to improve of nitrogen and other macro and micro-elements absorption which enhancing the production and translocation of the dry matter content from source to sink (El-Wehishy and El- Hafez, 1997;Awad, 2001;Ebaid et al, 2005;El-Refaee et al, 2006;Ebaid, et al, 2007). RH is bio transformed of into organic fertilizer through vermicomposting (Lim et al, 2012;Shak et al, 2014). Also it can be used as a source of potassium for growth and yield of cowpea (Priyadharshini and Seran, 2010).…”

“…Take crops straw for example, it is not only valuable in improvement of soil properties and crop production (Shi et al, 2010;Tejada et al, 2008;Kasteel et al, 2007;Liu et al, 2006;Kumar and Goh, 2000), composted fertilizer (Lim et al, 2012), forage processing, biofuel production (Tian et al, 2013;Sun et al, 2010;Rasmussen et al, 2010;Han et al, 2009), and industrial utilization (Suzuki et al, 2007), but also in the research potential and utilizing prospects in the field of agricultural pests management (Cao et al, 2010;Han et al, 2010;Ma et al, 2013), environmental pollution abatement (Liu et al, 2012;Chen et al, 2008;Chen and Yuan, 2011;Jones et al, 2011), etc. (Duan et al, 2012Woolf et al, 2010).…”

a b s t r a c tLaboratory biological simulation experiment was conducted to investigate growth disturbance of high, moderate, low concentration of aqueous extracts (i.e. the original extracts with a solid-liquid ratio of 1:40 g mL −1 and its 5 times diluents and 25 times diluents) from several crops straw (residue) on Ageratina adenophora, a worldwide notorious invasive weed. The results showed: (a) aqueous extracts from several crops straw (residue) brought about different impacts on the single index for germination and growth of A. adenophora, e.g., high concentration of aqueous extracts from Brassica oleracea waste leaves showed a strong inhibition against the germination rate (GR) and germination index (GI) of A. adenophora, while high concentration of aqueous extracts from Vicia cracca straw showed a strong inhibition against radicle length (RL) and hypocotyl length (HL) of A. adenophora; (b) high concentration of aqueous extracts from B. oleracea waste leaves and high, moderate and low concentration of aqueous extracts from Oryza sativa straw and Triticum aestivum straw showed rather strong synthetic effects (inhibition) on GR and GI of A. adenophora, which could be chosen for the control over the seeds germination of A. adenophora; (c) high and moderate concentrations of aqueous extracts from V. cracca straw, high concentration of aqueous extracts from B. campestris waste leaves, and moderate and low concentrations of aqueous extracts from O. sativa straw and T. aestivum straw showed rather strong synthetic effects (inhibition) on RL and HL of A. adenophora, which could be selected as ideal materials for the control over the seedlings growth of A. adenophora; and (d) high concentrations of aqueous extracts from V. cracca straw, B. oleracea waste leaves and B. campestris waste leaves, and high, moderate and low concentrations of aqueous extracts from O. sativa straw and T. aestivum straw showed rather strong synthetic effects (inhibition) on GR, GI, RL and HL of A. adenophora, which could be selected as ideal materials for the control over the seeds germination and seedlings growth of A. adenophora. Thus, this study would provide a theoretic guidance and technical support for the resources utilization of crops straw (residue) and the prevention and control over invasive weeds as well.
